EDN Access–12.18.97 Graphical technique lets you optimally bias bipolar-junction-transistor circuits

Biasing an active device, such as a bipolar junction transistor (BJT), requires that you set the dc voltages and currents of the device. To optimize the desired result, you need various bias values.
